The tasksche.exe file is a main executable process of WannaCrypt 2.0 ransomware. In short, this process installs along with all other modules of Wanna Decryptor and rights itself in a registry of your system. This will allow tasksche.exe to start along with Windows every time. Before trying to do anything with your encrypted files, we advise you to remove all files associated with Wanna Decryptor
There are three versions of Wanna Decryptor at the moment of this article being published. Each one differst from the other and tasksche.exe files are not the same. Though computers can be infected by several methods, the tasksche.exe file will have the same location:
[installation_folder]\tasksche.exe
After the encryption process is over, this process will right itself in the registry key:
HKCU\Software\Microsoft\Windows\CurrentVersion\Run\[random]
The process of encryption is quite similar to other ransomware. WannaDecryptor uses same algorithms and changes file extension in order to mark it.Example of encrypted files:
b.wnry c.wnry r.wnry s.wnry t.wnry u.wnry
